etc/rc.d/random_seed: revision 1.9
Don't delete the random seed before issuing `rndctl -S'.
`rndctl -S' can replace the file just fine, and deleting it ahead of
time adds a window during which we can lose the seed altogether if
the system is interrupted by a crash or power outage.
XXX pullup
rc.d/random_seed. The new dirname shell function provided by rc.subr
will be used, so it should work before the /usr file system is mounted.
This should fix a problem in which the fs_safe shell function failed when
passed the name of a file that did not exist.
- no need for "dirname", because "df -G" can take a file name directly.
- replace use of "awk" with a shell while read loop.
- replace use of "stat -s" with "ls -ldn".
- no need for "tail" now that the use of "stat" has changed.
While here, also add some shell quotes and improve the grammar in a comment.
after mountcritlocal. Everything else that runs after
mountcritlocal depends directly or indirectly on bootconf, so
making random_seed run before bootconf has the desired result.
at system shutdown. Disable with random_seed=NO in rc.conf if desired.
Goes to some trouble to never load or save to network filesystems.
Entropy should really be loaded by the boot loader but I am still
sorting out how to pass it to the kernel.
