Hi,

What about it? After installing a library (or when booting), I remount root
read-write, run ldconfig, then mount it readonly again. I (have to) do the
same when I want to update config files in /etc.

In situations where this isn't appropriate, /etc/ld.so.cache can easily be
symlinked off to /var/whatever, and /sbin/ldconfig can be patched to update
there.

Of course, I could have done the same with /etc/mtab, and used mount -n and
umount -n a whole lot, at boot and shutdown time. But the other advantage
of /proc/mounts (the first is, of course, that it can't get out of sync) is
that now three different mount commands won't block each other. This is
important when booting -- I usually do a parellel fsck+mount, and when two
of these are done at the same time, previously at least one mount command
would simply fail. Or they all would hang because another mount command
would be busy mounting all these slow NFS servers, and yet a third mount
command would scan the CD-ROM changer and mount all the CDs. (If you think
I'm crazy, you're probably not entirely wrong. ;-)

Well, no longer. Now all this is able to run in parallel, and I can
finally say "mount -atiso9660 &" in my /etc/rc.local, and have that
ampersand character actually _mean_ something.

A big Thank You to whoever put in the option handling for /proc/mounts.
