Thread: Consistency of an Installation

what ubuntu's strategy achieving , maintaining consistent installations?

scenario: have 2 oneiric installations, both started out regular 64bit desktop installations. manually added few packages on each of installations. don't remember packages , in sequence set and/or sequence different on 2 systems in question.

@ point noticed of shell scripts produced different results on 2 systems. further investigations showed 1 system had "gawk" other 1 had "mawk" default awk.

did not install *awk package on either system awk, mawk, gawk must have been pulled in because other packages had dependencies awk , seems installing additional packages, in different sequences, systems end differently resolved dependencies basic functions such awk.

can avoided? possible packages in repository have dependencies "awk", resolve pulling in exacly one version , flavour of awk? either gawk or mawk not both , not in non deterministic way.

in fact, talking "mawk", seems default, in 11.10 got pretty old version: 1.2, dated dec, 22, 1994 has known bugs in clamping unsigned integers signed integers. bug appears fixed since years not in v1.2

, while @ it: there way after facts investigate of installed packages pulled in mawk , pulled in gawk? @ least want know break on 1 of 2 systems if did "update-alternatives --config awk" , set same awk on both systems

to put plain, responsibility system administrator make sure both systems setup equally, if needed you. ubuntu (and no linux system know of) can you. different applications have different dependencies , hit y in both cases. make clear, not ubuntu installed on machine, told install on machine.
