Re: [Astlinux-devel] Adding a "spinner" indicator when e2fsck is working

[Lonnie A. <li...@lo...>]

Christopher,  AstLinux uses the latest e2fsprogs, we have all the options.

I don't have an example in front of me, but if it takes 15+ minutes for a "e2fsck -y /dev/sda2" then there must be a *lot* of fixes spewing on the screen, even without the -v option.  I'm not sure if opening up all of e2fsck's stdout is the best approach.
