Use case: I ITP etckeeper (https://etckeeper.branchable.com/) which I
frequently use on Debian. For fully automatic operation, it requires
pre-install and post-install hooks, e.g:
/etc/preremove/0p_000_etckeeper_pre-install.sh
/etc/postinstall/zp_zzz_etckeeper_post-install.sh
This patch adds the missing functionality to run the pre-install hook.
It is limited to /etc/preremove/0p_* because there is possibly no use
case for /etc/preremove/zp_*.
Thanks.
I'm not sure what you mean by 'there is possibly no use case': That you
don't have one currently, or that you've reasoned that there can't be one?
'class Perpetual0RemoveFindVisitor' is borrowed from postinstall.cc and
modified. It still uses the ugly pre-C++11 hack to disable copy-ctor and
operator=. Possible refactoring like merging all 3 mostly similar
visitors into one (or if C++11 is now allowed, use lambda functions
instead) are left for later.
Yeah, some refactoring would make this simpler and easier to understand. :)
I applied this patch.
Can you please also write a patch for [1] (source in [2]) to document this?
