but it doesn't need the block devices nor most partitions, so
this can use a customized MAKEDEV to avoid making those.
(I'd rather not enlarge the ramdisk image right now.)
have time to make the install tools handle release.7 layout.
Restore the change mycroft made in revision 1.3 (accidently
removed in my previous commit). Update sizes again.
so we can be sure there are no float instructions.
Nothing in here uses floating point, and this saves
space by avoiding the FPU_EMULATOR in the kernel.
(like upgrade but without trying to save etc.
* Add option to setls0urce menu to look in an already-mounted (local)
directory. Change `local fs' option to say umounted local fs.
* Change extract_file() to check that a tarball actually exists
and give an explicit non-curses warning if it doesn't. (see above.)
* GNU tar returns a successful status if its gunzip child dies.
Add short sleep() after tar commands in case of undetected errors.
* Change set-source selection code (except FTP, floppy) to check
that the mandatory set files (base.tgz, etc.tgz) exist
in the selected directory. If they don't, warn the user and
prompt the user to change the selected directory.
Give the user the option to explicitly continue even if
base.tgz or etc.tgz not found, just in case.
* Change extract_file() to keep count of set unpacks that succeeded
or failed. (Unreliable, given the broken return status of gnu tar.)
Warn the user if there are errors and abort the installation/upgrade
if we find any. Does at least catch Ctrl-C interrupts of unpacking.
* Make unwind_mounts() signal-safe.
* Sense of target_verify_* is broken. Replace with predicates that
return 1 iff the file or directory exists.
* Fix upgrade tests for existing etc.old (see above) before saving
target /etc as /etc.old.
* Other detail fixes.
* Add `partinfo' type, for description of a single partition,
so we can pass labels by reference..
* Add label.c with label initialization, naive overlap-check code,
and a UI entrypoint edit_and_check_label() which iterates through
checking a label for overlaps, and if any, giving the user the choice of
fixing them or punting back to the main menu.
* Change return type of md_make_bsd_partitions from void to int.
Return 0 if the partition has problems (or the user gave up on it)
and 1 if the partition is completed and looks OK.
* Change install() to check return value of md_make_bsd_partitions().
If it returns zero, print an `abort' message and return to main menu.
* Add label.c to all ports' Makefile.
MD code tested on pmax and cut-and-pasted to other ports.
* Add mount_with_unwind() that adds mountpoint to a LIFO queue
of mountpoints to undo on error. Use in target_mount().
* Add unwind_mounts() which traverses the LIFO queue and unmounts
filesystems, silently ignoring errors.
* create toplevel() function which displays banner message and
calls unwind_mounts().
* change toplevel menu to call toplevel() instead of inline banner.
Where to do unwinds needs more thought. Perhaps we should only unwind
if an upgrade or install appears unsuccessful, so after a successful
install, the target is mounted (e.g., for upgrading /etc/rc.conf).
at used partitions. fdisk may report the number of cylinders > 1024
correctly if no translation is used.
* Print out the end of the partition as well as the size when editing things.
* Enable the user to specify the BIOS geometry if he/she wishes.
* Fix 1023 / 1024 mixup. The reason BIOSs will return 1023 is an old IBM
convention to use the last cylinder as diagnostic cylinder. The user
can still skip the last ('real') cylinder if specified.
* Make some messages more verbose.
all pathname-on-server related definitions to MI code, since they are now
defined to be consistent across all platforms. Also, nuke the "rels" global,
since release numbers are now always specified in "long form", i.e. 1.3A
vs. 13A.
* Create target /kern after creating target /etc/fstab entry for /kern.
* Check for more files in target when done: /etc/{rc,rc.subr,conf}
* Clean up warning exerciser.
o Added recently supported hardware
o Noted setup of rc.conf in install
o Added a new upgrade procedure
o Explained 1.3 enhancements in whatis
o Converted Mac-side utility names to be more version independent
ext_dir that is absolute directory name of where files are located to
extract. All setup routines must set that directory name correctly.
Make target.c compile if DEBUG is set.
If installing from a pmax diskimage as both current root and target root,
the diskimage /usr/bin/tar is hidden underneath the target /usr mountpoint
when it's time to untar distribution files. From a comment in the change:
Make sure any binaries in a diskimage /usrbin get copied
into the current root's /usr/bin. (may be same as target /usr/bin.)
The rest of sysinst uses /usr/bin/{tar,ftp,chgrp}.
We cannot ship those in /usr/bin, because if we did
an install with target root == current root, they'd
be be hidden under the target's /usr filesystem.
Requires updated diskimage build script which populates /usrbin with
tar, gzip, gunzip, ftp, and chgrp (all statically linked.)
and current-root-is-target-root (pmax diskimage.
* Add code to check disk names (e.g., "sd0") against the current
kern.root_device sysctl (whic does *not* include a partition).
* Add new function must_mount_root():
check to see if it's the same device as the root. If not,
the current and target root partitions cannot overlap.
If they do, do statfs() on "/", and return 1 iff we get back
"root_device" as the mounted-on filesystem, otherwise zero.
* Call must_mount_root() right after the user specifies a disk as
install/upgrade target, and if it returns 1, print a message asking
them to mount root, and abort.
* Use statfs("/") mounted_from string to check if a disk partition
(e.g., "sd0a") matches the current root.
as last step of upgrade, so /etc/fstab exists after reboot.
* util.c: correct sense of test in sanity-check helper check_for().
Change variable name to `found' for readability.
still needs an option to specify the distribution sets from a filesystem
present in fstab.
Add "ados" to the list file recognized filesystems.
Increase label information table size to 16 to allow for 16 partitions.
* Change find_disks: after mouting target root, check for
/etc/fstab in target, and abort upgrade if not found.
* Change upgrade to check if the target root has /etc.old
before renaming the target /etc -> /etc.old. If found, abort.
(may indicates a failed upgrade.)
* Add save_etc(). saves target /etc as /etc.old, then copies back
config files we might want during upgrade, in case target is current root.
* Fix logic that fscks and mounts disks. Use subroutines to
fsck with a warning message and ok() on continue. Same for doing mounts.
* Fix bug in extract_dist(). Do NOT do target prefixing on the dist_dir,
since we didn't do target prefixing when mounting it.
(At least, NFS does't.)
* Add function to sanity-check target root.
Call after upgrade/install is done.
* Change MSG_realdir to print the strerror() of any errors.
Change target_chdir() to check if chdir() returns -1 and return errno.
* Make sure /dev exists before cd'ing there and running MAKEDEV.
* Use target_fopen() and fprintf() to write network state to disk,
to avoid inadvertent shell escapes.
* Fix silly typo in append_to_target_file. (maybe add shell quotes?)
- Added -r rel flag to change the release tag on the tar files.
- Added Usage
- Fixed a menu bug (missing exit)
- Made target_expand available to all functions to produce correct
file names.
Add more #ifdef DEBUG to target-prefixing.
* Fix niggle in creating a new resolv.conf: ctime()'s result ends in '\n',
so don't include one after the %s for the timestamp.
* Change upgrade: add the same ``disk stuff done'' message used in install,
so the user knows what's going to happen.
(is a more tailored message useful?)
* Correct arg typo in mv_within_target_or_die().
* Add new path-prefixing entrypoints to fopen(), collect(), and do mounts.
* Use the above. MI code is now clean of explicit references to /mnt.
* Lint: add `const' to collect()'s pathname arg.
include <stdio.h> in factor.c, now that defs.h uses FILE*.
* Put newfs-and-mount code into a separate function, in case
we want to support non-ffs filesystems.
* Check for the currently-mounted root, and don't newfs or mount it.
Assumes md code will also avoid changing that partition.
* renames of files from one pathname within the target to another
(e.g., mv_within_target_or_die("/etc", "/etc.old");
* check to see if a partition name like "sd0a" is the current root
* Duplicate a file from the current root into the target root
(for copying /netbsd from RAMdisk into the target).
A no-op if the root is the install target).
Start using these where appropriate.
Change net.c to avoid losing any information when updating network
config files: where possible, do appends to files that might have more
info than we got from the user (e.g., /etc/hosts.)
Where possible, add comment saying file was created/modified by sysinst.
Add target.c to Makefiles.
* Minor fixes:
* Fix buglet in disks.c: make sure the target /etc exists before
touching the target's /etc/fstab. (Could be even cleaner.)
* If the target root is on /, don't copy our temporary /etc/resolv.conf
to the target /etc/resolv.conf. (Could be even cleaner.)
* Don't write the DNS hostname into /etc/defaultdomain.
DNS search paths are often not the same as YP group names.
run_prog_or_die() -- aborts if system() returns an error.
run_prog_or_continue() -- prints a warning that installation may
have failed but lets the user continue. Suitable for running mkdir.
