From 18f368fa35269aba4ad444d3a4bae06d4608a2c8 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Fri, 22 Jul 2016 13:18:41 +0300 Subject: [PATCH] linux: Get rid of 000-keep_initrafs_the_default.patch MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit With that patch in place for initramfs no additional options are reported for "/" partition. What's really important is missing info about sizes. Which in its turn makes opkg think that there's no space on "/" partition to install software. I understand that's a sort of corner-case, people rarely install packages on ramfs but anyways why not? Just in case that's what I see with the patch: ---------------------->8-------------------- root@lede:/# cat /proc/mounts rootfs / rootfs rw 0 0 proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0 sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0 tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0 tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0 debugfs /sys/kernel/debug debugfs rw,noatime 0 0 ---------------------->8-------------------- And without: ---------------------->8-------------------- root@lede:/# cat /proc/mounts rootfs / rootfs rw,size=256168k,nr_inodes=32021 0 0 proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0 sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0 tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0 tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0 debugfs /sys/kernel/debug debugfs rw,noatime 0 0 ---------------------->8-------------------- Note how different is entry for rootfs. And given there's no known rationale for that patch we're getting rid of it.
