Solved: mdadm can I delete?

I went to Sid on one flavour (siduction), I started seeing mdadm messages early on saying  (retrieved via journalctl -g | grep mdadm)

Dec 02 22:31:54 rauneseee mdadm-raid[204]: Assembling MD arrays...done (no arrays found in config file or automatically).

System has 1 ssd /sda1 is / /sda2 is /home and sdhc for /dev/sdb2 is a swap.  No raid.  I have looked around some and I do not see any down side to apt-get remove mdadm

This has jumped up higher on my possible to-do list via the bug for mdadm 771852.  Is it probably quite safe to remove mdadm for people with simpler file systems?    And yes, I will  unhold mdadm from dpkg before should I decide to remove it.

peace Mark

edit later, other confirmation in a thread over at siduction.  -- No I did not start or continue  that thread.      I only asked once and only here cuz y'alls so nice.

Re: Solved: mdadm can I delete?

Just use this and read what APT says it wants to do:

sudo aptitude purge mdadm

If it's part of a tangled web of dependencies, aptitude will offer you several options whereas apt-get will just ask for confirmation to remove everything.

If you're not using RAID, it should be OK to remove it.

OTOH, that's not an error message so why bother removing it?

The bug you mention gives a "failed to load MD subsystem" message -- you do not have this...

Well, one can always check the dependencies:

Or some really heavy duty lists:

## CHECK DEPENDENCIES OF PACKAGES
##   depends shows a listing of each dependency a package has and all the
##   possible other packages that can fulfill that dependency.
alias dep='echo "alias dep=apt-cache depends" && apt-cache depends'

##   rdepends shows a listing of each reverse dependency a package has.
alias rdep='echo "alias rdep=apt-cache rdepends" && apt-cache rdepends'

##	or OMG it's a list of depends depending on depends
alias rrdep='echo "alias rrdep=apt-rdepends" && apt-rdepends'
