Subject: Re: Alternatives after removal of ReiserFS

Hello Jan and Oleksandr,

I would prefer to avoid btrfs if possible. It ate my Gentoo root 
filesystem in 2017. This incident has been resolved by reinstalling the 
system because each attempt to fsck only made it even worse. I 
appreciate it for excellent transparent compression and for generally 
good support for Docker, but I can live without it.

 >But given how cheap the storage is these days, people don't care as much.

I don't like this kind of attitude because it encourages a decline in 
quality in general. We'll learn to appreciate what we have once it 
becomes scarce again.

Thank you Jan and Oleksandr very much for your knowledge on xfs and 
ext4. I'll make sure to put it to good use.

Bestest regards,

Michał Dec
