Hello list, this email is a follow-up of: https://www.mail-archive.com/linux-f2fs-devel@lists.sourceforge.net/msg14390.html
I will number the questions Q1, Q2 etc. To summarize the context and goal: I want that the Slint installer format the root partition with f2fs when appropriate, if possible without asking questions to the user about the device. I target usage of f2fs for the root file system in cases of USB flash drives aka USB sticks, SD cards, eMMC, as if I understand correctly these kinds of devices benefit the most of wear minimization and increase of performance when using f2fs. I plan to use ext4 for SSD (including NVMe) and hard disks. This leads to several questions: Q1: Comments about this choice of target devices for f2fs, knowing that I favor security over performances and that the "auto" option of the installer is intended for your grand-mother? I am a grand father myself <smile>. Q2. How-to determine if the drive fall in one of the types listed above without asking the user if possible? I have considered using the output of lsblk and/or "udevadm info" but that doesn't seem to provide enough information on the device. As an aside, I have seen rota=1 for an USB boot stick. ??? Q3. What would be the safest options to include in the relevant line of /etc/fstab forthe root partition using f2fs? Q4. do you confirm the statement below? it is a quote of web page: https://wiki.gentoo.org/wiki/F2FS > When using f2fs > When using f2fs as rootfs fsck fails on boot. > Solutions are either disabling fsck in /etc/fstab (setting the last > number to 0) or enabling the force-flag for fsck in /etc/conf.d/fsck. > See bug #671786 Q5. I am correct f2fs can be expanded but not shrinked. Is it still true? Will it planned to bring this feature? Q6. Currently we ship a 4.19 kernel. Would it be preferable to ship a 5.4 one instead shipped in Slackware-current at time of writing, knowing that we ship an no patched (aka vanilla) kernel and what would be the benefit of doing so wrt f2fs? Have a good day, Didier _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
