When upgrading Cumulus Linux to a new version, which configuration files should be migrated from
the old installation?
Pick the 2 correct responses below.
Maybe B and D? I know /etc/network is definitely needed, but /etc/mix sounds like it might hold some Spectrum-X specific configs, so could be important too. Definitely not all of /etc though.
Makes sense to skip C since it’s way too broad and could mess with unrelated settings. D looks suspiciously niche, so A and B seem the safest bets. A, B
A vs B? I’m going with A and B too. /etc/cumulus/acl holds the access control lists, which you definitely want to keep, and /etc/network contains essential network settings. C is too risky since /etc has loads of unrelated stuff that might mess things up if copied wholesale. D seems like a made-up directory or something less relevant here. So sticking to just the key config folders related to ACLs and networking makes the most sense.
It’s A and B because ACLs and network configs are essential, not the whole /etc or just /etc/mix.
A imo, since ACLs are crucial for security policies, and B makes sense for network settings. D looks too niche and C is way too broad, could cause issues if you migrate all of /etc.
Good point about not wanting to mess with everything in /etc. I’d go with B and D since network configs and /etc/mix seem critical for Spectrum-X specifics. A might be too narrow. So B and D.
A/B for sure, C is way too broad and risky.
A imo, since ACL files are specific to Cumulus and likely not overwritten during an upgrade. Avoid C because migrating all of /etc could cause conflicts with new system files.
A, B. For me, A makes sense because ACL configs are usually custom and important to keep. B also seems right since network settings under /etc/network are essential for connectivity, so you'd want to bring those over too. C is too broad—migrating everything in /etc might cause conflicts or bring unnecessary files. D doesn’t sound familiar or standard for Cumulus, so probably not.
B tbh, but do we know if the question assumes a full OS upgrade or just a patch? That might change which config files need migrating.
