Talk:Installing Arch Linux on a USB key
Before creating the initial RAM disk (mkinitcpio)
The correct custom configuration of the initial RAM disk is a step that very few users of arch need to do so is a thing that needs to be highlighted for this use case. Also the placement of this information in Installation tweaks makes it appear that is optional so i think that it will be better if the information is moved to configuration.
I am experiencing serius I/O errors after suspending / resuming with arch on a usb key. These issues have been described in several bugreports: https://bugzilla.kernel.org/show_bug.cgi?id=30912
I tried following the steps in https://www.kernel.org/doc/Documentation/usb/persist.txt
but to no avail. The usb persist feature was already activated on my USB deve but I/O errors kept coming on resume
I also found this post in ubuntuforums
which explains the issue as follows
"...during resume there will be a race between the USB system on one hand trying to detect media and syslog on the other hand trying to write log messages from suspend and resume to disk.
If syslog happens to attempt a write before the USB device has been detected ext4 gets an error, which for some reason isn't handled cleanly and eventually the file system will need fsck to be run manually."
The author suggest patching the kernel to give kernel threads a head start on resume. Intuitively, I feel there must be an easier way!
