>Release: FreeBSD 4.1-STABLE i386
>Organization:
Southern Ural State University, Chelyabinsk, Russia
>Environment:
i386 workstations boot FreeBSD 4.1-STABLE remotely from the server with
the same OS using rc.diskless* scripts. / and /usr are monted from
the server (actually the server's / and /usr), /etc and /var are
mounted by rc.diskless2. /tmp and swap are mounted from local disks.
>Description:
/etc/rc checks $1 against "autoboot" after it runs /etc/rc.diskless1.
But as the latter uses "set" command, it clears the command line, and
so /etc/rc fails to check for autoboot mode, so it doesn't run fsck,
and so fails to mount local filesystems (/tmp in my case).
>How-To-Repeat:
Ensure you have /etc/rc.diskless* on the file server, boot
FreeBSD 4.1-STABLE remotely from this server, and specify some
locally mounted filesystems in /etc/fstab (ensure you have "1" in
the 6th column for these filesystems. Then do a "dirty" reboot
of the remote-booting machine (with reset button), and watch the
booting process: instead of running fsck it prints "Skipping disk
checks...", and then fails to mount local filesystems because they
are still not clean.
