rescue
RESCUE(8) BSD System Manager's Manual RESCUE(8)NAME
rescue -- rescue utilities in /rescue
DESCRIPTION
The /rescue directory contains a collection of common utilities intended for use in recovering a badly damaged system. With the transition
to a dynamically-linked root beginning with FreeBSD 5.2, there is a real possibility that the standard tools in /bin and /sbin may become
non-functional due to a failed upgrade or a disk error. The tools in /rescue are statically linked and should therefore be more resistant to
damage. However, being statically linked, the tools in /rescue are also less functional than the standard utilities. In particular, they do
not have full use of the locale, pam(3), and nsswitch libraries.
If your system fails to boot, and it shows a prompt similar to:
Enter full pathname of shell or RETURN for /bin/sh:
the first thing to try running is the standard shell, /bin/sh. If that fails, try running /rescue/sh, which is the rescue shell. To repair
the system, the root partition must first be remounted read-write. This can be done with the following mount(8) command:
/rescue/mount -uw /
The next step is to double-check the contents of /bin, /sbin, and /usr/lib, possibly mounting a FreeBSD rescue or ``live file system'' CD-ROM
(e.g., disc2 of the officially released FreeBSD ISO images) and copying files from there. Once it is possible to successfully run /bin/sh,
/bin/ls, and other standard utilities, try rebooting back into the standard system.
The /rescue tools are compiled using crunchgen(1), which makes them considerably more compact than the standard utilities. To build a
FreeBSD system where space is critical, /rescue can be used as a replacement for the standard /bin and /sbin directories; simply change /bin
and /sbin to be symbolic links pointing to /rescue. Since /rescue is statically linked, it should also be possible to dispense with much of
/usr/lib in such an environment.
In contrast to its predecessor /stand, /rescue is updated during normal FreeBSD source and binary upgrades.

The rescue utilities first appeared in FreeBSD 5.2.
AUTHORS
The rescue system was written by Tim Kientzle <kientzle@FreeBSD.org>, based on ideas taken from NetBSD. This manual page was written by
Simon L. Nielsen <simon@FreeBSD.org>, based on text by Tim Kientzle <kientzle@FreeBSD.org>.
BUGS
Most of the rescue tools work even in a fairly crippled system. The most egregious exception is the rescue version of vi(1), which currently
requires that /usr be mounted so that it can access the termcap(5) files. Hopefully, a failsafe termcap(3) entry will eventually be added
into the ncurses(3) library, so that /rescue/vi can be used even in a system where /usr cannot immediately be mounted. In the meantime, the
rescue version of the ed(1) editor can be used from /rescue/ed if you need to edit files, but cannot mount /usr.
