before extracting sets, and move it back afterwards, to save the information

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.
- Make all the functions called from do_install() return an error code,
so that we can abort install if something went wrong.
- Add a 'errstr' argument to run_prog(), which if not NULL is displayed
with msg_printf() and followed by process_menu(MENU_ok) if the command fail.
Used to warn the user that the current action is aborted.
- in a few places use msg_display() or msg_printf() rather than printf.
It seems that stdout/stderr are not always pointing to the active curses
window.
- garbage-collecd unused messages, add a few new one (error handling).
XXX only tested on i386. Other md parts should be tested as well.
commandlines for all tar operations. (work supplied by Matt Green)
2) Update arch/*/md.c to deal with new sysinst/run.c. Special case
anything that needs to do a redirect or a pipe.
3) #if 0 some unused code in target.c. This code will need to be updated,
or special cased with do_system.
Big thank you to Matt for all his work on this.
Scripting and logging functionality for sysinst.
Child programs are run in a "display window" so you can actually see what
they did before the screen flashes back and you loose it all.
Lots of curses fixups. Removed nasty endwins that mangled the tty upon
rentry.
Change the yes/no box to accept Y or N, and not require cursor motion to
decide one or the other.
Perform curses redraws when doing things that could cause the kernel to
spew printfs onto your screen.
* Add cp_to_target() to copy a file from current root, to an absolute
path relative to target root.
* Clean up alpha, arm32, i386, pmax MD code: use cp_to_target()
NB: Alpha uses target_expand() when calling installboot.
* Add tests for target == current root. Intended to support
`upgrade/reinstall' to current root, either for testing or easier
minor-release upgrades. Only tested on pmax.
(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 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).
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.
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.
* 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*.
* 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.
