Hi, I'm the schroot/dchroot maintainer. I missed the initial question, but I'd just like to note that - the dchroot behaviour had an unintentional backward-incompatible change in the options parsing and command execution. This has since been corrected; it's currently waiting in NEW and should enter sid in a week or so. In the meantime, it's available from https://alioth.debian.org/project/shownotes.php?release_id=816 https://alioth.debian.org/download.php/1654/schroot-0.99.1.tar.bz2 - schroot allows any number of command-line options, e.g. $ schroot -c chroot -- foo --opt1 --opt2 bar baz - dchroot allows a single command, but invokes it automatically via "sh -c": $ dchroot -c chroot "foo --opt1 --opt2 bar baz" The schroot syntax (which dchroot in sid is transiently using) is rather more flexible, but if you want the dchroot semantics just requires '-- sh -c "command"' instead of 'command'. > Isn't the syntax in that original command, you posted from the bug report > actually telling the command dchroot to *ignore* any following 'options', by > using the ' -- ' syntax, just after the command...IOW > > Doesn't this; >> dchroot -- -c "command" > mean: dchroot, ignore options that follow, then pass to it the -c > option (which it may ignore?), then "command".? This would mean run the "-c" program with "command" as the first option (!). Probably not quite what is desired. > I only ask b/c, I've learned (from lurking about usenet) that this > is one trick that's used to remove filenames that begin with a '-' > (hyphen), when using the 'rm' command. Yes. It's used here so that dchroot/schroot can distinguish between options for themselves and options for the program you want to run. For example, schroot ls -l and schroot -- ls -l are different. With the former, schroot gets the "-l" option, but with the latter ls gets it. BTW, any dchroot/schroot questions are welcome on the buildd-tools-devel mailing list.
