Anybody with any words of wisdom about using hg for system config
files?  I've been using hg only for source code so far.  The first
issue that comes to mind given my experiences is that hg doesn't yet
support symlinks.

Sorry for being dense but that "requirement" still doesn't make any
sense to me.  If you're using a DSCM model then where is your need for
locking?

No worries!  Always good to try and figure out different uses.

Take care,
