I've been using \ to continue a line in /etc/exports, and ran into an
odd problem -- if you accidentally hit the TAB key after the continue
line and save, the entry becomes invalid. Since the TAB key is
invisible, it can be difficult to figure out what's going on.
I reported it as Debian bug 418491 to nfs-kernel-server, and the
maintainer responded by saying \ isn't a valid continue character.
Comments? I routinely do this sort of thing:
/spare \
165.97.21.130(rw,no_root_squash,no_subtree_check,async) \
165.97.21.132(rw,no_subtree_check,async) \
165.97.21.133(rw,no_subtree_check,async) \
165.97.21.134(rw,no_subtree_check,async) \
165.97.21.135(rw,no_root_squash,no_subtree_check,async) \
165.97.21.136(rw,no_subtree_check,async) \
165.97.85.112(rw,no_subtree_check,async) \
165.97.85.117(rw,no_subtree_check,async)
A lot easier to maintain that a single line. Is there an alternative way
to continue the line?
Cheers,
Dave

Thus, closing this one; forgot to do so last time.

Once you know about this quirk, it's obviously less of an issue. Still, if I imagine trying to help myself in the past from this enlightened position in the future, it would be fun to come up with a more user-friendly solution. Could exportfs just filter out TAB characters, or would you consider that unwanted code clutter? Dave ------------------------------------------------------------------------- Take Surveys.

Well, he's right. As far as I remember the line continuation has always been "\<NL>", otherwise you get a solitary <NL> which would end the entry. > Comments?
