1) Debian *doesn't* have GNU sed? I'm pretty sure such a Debian install
would make sed -i available, so that sounds like a bad example. However,
I understand the force of your argument, and that still holds. That
problem could be mediated by having more diverse SMGL basesystem chroots
available. Any volunteers to automate builds for more architectures?
2) sedit on SMGL is provided via part of sorcery itself, and isn't
available as a binary. According to [1], it currently just runs sed -i
anyway, so calling the sorcery sedit on a system lacking GNU sed will
still fail.
Alternatively, a roundabout (and slower) means of editing a file "in
place" can be done by piping output to sed, having sed act on the
stream, and then storing the output back to the same file via pipe or
similar.
Example: cat FILE | sed -e 's/something/ELSE/' > FILE
That example should always work as long as both sed and cat are
available, regardless of the version of sed. It should also, in theory,
work regardless of the shell being used (inputting the file via (<FILE)
is a bash-ism). Perhaps having a "backup" sedit in sorcery would be a
good idea? Though, in my opinion, only if we have a smart way of
detecting if GNU sed is installed and using sed -i by default since that
would be much faster. This is tough to do, since checking on each run of
sorcery would slow it down, but having it set in a config file, while
faster, wouldn't make much since, because at that point you might as
well manually call sed/sedit/whatever anyway.
