on my system is btrfs only needed for some external disks. So I do not need and do not want a startup delay about 15s for a scan at startup.

Does someone know how to tell the ubuntu startup scrippts not to check for that filesystem at startup. I found in here some people does purge than the btrfs but this is for me no solution as I want tu use the mudule sometimes.

I found the following answer:

modify the file /usr/share/initramfs-tools/scripts/local-premount/btrfs

I did only insert a # in the line where the btrfs scan is called.

than did the following commands:

update-initramfs -uk all


now the module gets loaded but the scan is suppressed while startup.
