NAME
savecore - save a core dump of the operating system
SYNOPSIS
/etc/savecore dirname [ unix ]
DESCRIPTION
Savecore saves a copy of the physical memory of the operating system,
saved after a system crash. It is meant to be called from rc(8) after
normal filesystems are mounted.
Savecore checks the core dump to be certain it corresponds with the
named unix (default `/unix'). If it does it saves the core image in
the file dirname/core.n and its sibling, the namelist, in
dirname/unix.n. The trailing `.n' in the pathnames is replaced by a
number stored in dirname/bounds which grows every time savecore is run
with the same dirname argument.
Before savecore writes out a core image, it reads a number from the
file dirname/minfree. If there are fewer free kilobytes on the
filesystem which contains dirname than the number obtained from the
minfree file, the core dump is not done. If the minfree file does not
exist, savecore always writes out the core file (assuming that a core
dump was taken).
FILES
/unix current unix binary
dirname/bounds numerical suffix
dirname/minfree minimum free kilobytes required
