to the toplevel menu, as promised by the media selection menu, without
first going through an "installation is aborted" menu.
* when something causes the installation to fail (e.g. missing set or failure
to extract a set's contents), don't go through N menus
(missing/failed/aborted, sets didn't install/aborted,
sanity check failed/aborted) before getting back to the top level. The
user only needs to be told once that their life sucks.
screen as XXX. Where they were not followed by wclear(stdscr), add
wclear(stdscr). Somebody was let out without adult supervision. If i
were more adventurous, i'd remove the bits that output 'CL', but i'm not
gonna go there right now.
cleanups before extracting a set. Should'nt do anything for an install,
as the filesystem shouldn't contain files that need to be removed.
cleanup_dist() is called before extract_file() for each set (the set name
is passed as parameter). It will open a file /dist/<set name>_obsolete
if it exists. This file should contain a list of files (absolutes
pathnames) that needs to be removed. cleanup_dist() will lstat() each file
to determine if it's there and if it's a directory or not.
It will then unlink() entries that are not directories and then rmdir()
directories. If a directory is not empty (it should now if the list of files
is correct) it will be renamed to <directory.old> and the user will be warned.
Other changes:
- move prototype of target_prefix() in defs.h, don't maintain a copy
of it in each file.
- in install.c, after MSG_disksetupdone, do a wclear(stdscr) (display was
clobbered after it).
- kill MSG_openmsgbuf, it's not used anywhere
- after MSG_disksetupdone in upgrade, don't call MENU_ok, do it the
same way as in install.
- add wclear(stdscr);/wrefresh(stdscr); before calling MENU_distset (another
display problem ...)
- While I'm there, move ask_verbose_dist() before MENU_distmedium. This way,
if all go well the user can go away one ftp starts and come back once
sets are extracted.
(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.
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.
* 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?)
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?)
* 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.
parallel development. i386 version about 90% complete. pc532 version
just started, other architectures later in coordination with portmasters.
This is a curses based, menu driven installation program.
Better error checking is needed.
