Why would a 'mount -a' not work after your 'umount -a' to restore the mounts?

Because Cygwin's mounts aren't the same as Unix mounts. The mount and umount commands on Cygwin modify the mount table directly, so that a umount really is permanent. However (and this concerns the OP, too), you can save the mount table as the output of "mount -m", which you can later use to restore the mounts.
not really.
I used to do that quite often, but since /bin and /usr/bin are not known to cygwin anymore after umount -a (and not in the path) I came with this workaround.
#!/bin/sh # save mounts BIN=`cygpath -w /bin | sed 's|\\\\|/|g'` mount -m | sed "s|^mount|$BIN/mount|" | tee savemounts umount -a
# nano or $EDITOR will not work now to fix savemounts!
# restore . savemounts
it will look like "f:/cygnus/bin/mount" now. This will be found, on NT at least.
For those unfortunate enough to have done a "umount -a" without saving the mounts via "mount -m", the minimum necessary mounts for Cygwin to work are
mount -sbc /cygdrive mount -fsb c:/cygwin / mount -fsb c:/cygwin/bin /usr/bin mount -fsb c:/cygwin/lib /usr/lib
(that is provided that you installed Cygwin in c:/cygwin).
