Just Did a simple Fedora 15 Alpha “minimal” Installation with btrfs as root Filesystem. Then I did some checks and want to see if its really btrfs mounted:
[root@localhost ~]# mount /proc on /proc type proc (rw,relatime) /sys on /sys type sysfs (rw,relatime,seclabel) udev on /dev type devtmpfs (rw,nosuid,relatime,seclabel,size=503504k,nr_inodes=125876,mode=755) devpts on /dev/pts type devpts (rw,relatime,seclabel,gid=5,mode=620,ptmxmode=000) tmpfs on /dev/shm type tmpfs (rw,relatime,seclabel) /dev/mapper/VolGroup-lv_root on / type btrfs (rw,relatime,seclabel) none on /selinux type selinuxfs (rw,relatime) udev on /dev type devtmpfs (rw,nosuid,relatime,seclabel,size=503504k,nr_inodes=125876,mode=755) tmpfs on /sys/fs/cgroup type tmpfs (rw,nosuid,nodev,noexec,relatime,seclabel,mode=755) cgroup on /sys/fs/cgroup/systemd type cgroup (rw,nosuid,nodev,noexec,relatime,release_agent=/lib/systemd/systemd-cgroups-agent,name=systemd) cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset) cgroup on /sys/fs/cgroup/ns type cgroup (rw,nosuid,nodev,noexec,relatime,ns) cgroup on /sys/fs/cgroup/cpu type cgroup (rw,nosuid,nodev,noexec,relatime,cpu) cgroup on /sys/fs/cgroup/cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpuacct) cgroup on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory) cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices) cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer) cgroup on /sys/fs/cgroup/net_cls type cgroup (rw,nosuid,nodev,noexec,relatime,net_cls) cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio) systemd-1 on /sys/kernel/security type autofs (rw,relatime,fd=28,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) systemd-1 on /sys/kernel/debug type autofs (rw,relatime,fd=29,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) systemd-1 on /proc/sys/fs/binfmt_misc type autofs (rw,relatime,fd=30,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) systemd-1 on /dev/mqueue type autofs (rw,relatime,fd=32,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) systemd-1 on /dev/hugepages type autofs (rw,relatime,fd=33,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) tmpfs on /var/run type tmpfs (rw,nosuid,nodev,noexec,relatime,rootcontext=system_u:object_r:var_run_t:s0,seclabel,mode=755) tmpfs on /var/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,rootcontext=system_u:object_r:var_lock_t:s0,seclabel,mode=775,gid=54) /dev/vda1 on /boot type ext4 (rw,relatime,seclabel,barrier=1,data=ordered) hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime,seclabel) mqueue on /dev/mqueue type mqueue (rw,relatime,seclabel) [root@localhost ~]#
But it turns out that Fedora 15 added some more mounts 🙂 Thats not really so userfriendly, how would it looks like with some more bind mounts or Filesystems ?
