(Four images are built, linux (default, fallback), linux-hardened (default, fallback)) gzip: real 1m42.140s user 1m22.717s sys 0m23.493s lz4: real 1m1.120s user 0m44.310s sys 0m21.785s cat (without compression): real 0m59.477s user 0m43.050s sys 0m21.946s To sum it up I will enable lz4 compression to benefit from both reduced time and saving space. Also I'm planning to read wiki on how to safely disable fallback. I'm using LVM on LUKS method and I suppose fallback image cannot boot my Arch, so it doesn't help in case of an accident. Thank you all

[arch-general] Problems with files creation / copy with Samba 4.12.x and SMB1 only device.

Hello. Before all, thanks to David C. Radkin for the tweak related to SMB1 activation. After installing Samba 4.12.x, I added only this in [global] section of /etc/samba/smb.conf to get access to one of my old SMB1 only network based HDD: server min protocol = CORE client min protocol = CORE After a reboot, I got access to my share, but every single time I want to copy / create a new file, a folder is created! Of course, I cannot delete this folder. Here is an error log I had in /var/log/everything.log: Mar 31 23:28:40 fredo-arch-mate gvfsd[1096]: Kerberos auth with 'fred@WORKGROUP' (WORKGROUP\fred) to access '192.168.1.254' not possible Any idea? Thanks! -- Frederic Bezies fredbezies(a)gmail.com
