Subject: Add support for components override
X-Git-Tag: v0.12~2
X-Git-Url: http://git.equinoxoli.org/?p=ext%2Finstance-debootstrap.git;a=commitdiff_plain;h=1cfb9189a50eb02753d6e8ae965a09cb211ffac7

Add support for components override

This fixes issue 254. I've took a slightly different approach (never
pass --components if the variable is empty, to not override builtin
debootstrap default).
