--Apple-Mail=_3A7CEF12-6CD0-48EF-B7AE-B9193C5F13FD Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 Hi all, In the /boot/defaults/loader.conf are these options for memory disk = settings: #mdroot_load=3D"YES" # The "mdroot" prefix is arbitrary. #mdroot_type=3D"md_image" # Create md(4) disk at boot. #mdroot_name=3D"/boot/root.img" # Path to a file containing the image. #rootdev=3D"ufs:/dev/md0" # Set the root filesystem to md(4) = device. But - is this example for rootdev option still right? Because = =E2=80=9Cufs:/dev/md0=E2=80=9D works fine on freebsd 12.1, but on = freebsd 12.3 this does not work and generates error message: Can=E2=80=99t determine root device When I use this option with value =E2=80=9C/dev/md0=E2=80=9D or = =E2=80=9Cmd0=E2=80=9D (even with this option commented out), so the = machine boots correctly without any error. =E2=80=94 Mira= --Apple-Mail=_3A7CEF12-6CD0-48EF-B7AE-B9193C5F13FD Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=utf-8 <html><head><meta http-equiv=3D"Content-Type" content=3D"text/html; = charset=3Dutf-8"></head><body style=3D"word-wrap: break-word; = -webkit-nbsp-mode: space; line-break: after-white-space;" class=3D"">Hi = all,<div class=3D""><br class=3D""></div><div class=3D"">In the = /boot/defaults/loader.conf are these options for memory disk = settings:</div><div class=3D""><br class=3D""></div><div class=3D""><div = style=3D"margin: 0px; font-stretch: normal; line-height: normal; = font-family: "Helvetica Neue";" = class=3D"">#mdroot_load=3D"YES" = # The "mdroot" prefix is arbitrary.</div><div style=3D"margin: = 0px; font-stretch: normal; line-height: normal; font-family: = "Helvetica Neue";" class=3D"">#mdroot_type=3D"md_image" = # Create md(4) disk at boot.</div><div = style=3D"margin: 0px; font-stretch: normal; line-height: normal; = font-family: "Helvetica Neue";" = class=3D"">#mdroot_name=3D"/boot/root.img" # Path to a file = containing the image.</div><div style=3D"margin: 0px; font-stretch: = normal; line-height: normal; font-family: "Helvetica Neue";" = class=3D"">#rootdev=3D"ufs:/dev/md0" # Set = the root filesystem to md(4) device.</div></div><div style=3D"margin: = 0px; font-stretch: normal; line-height: normal; font-family: = "Helvetica Neue";" class=3D""><br class=3D""></div><div = style=3D"margin: 0px; font-stretch: normal; line-height: normal; = font-family: "Helvetica Neue";" class=3D""><br = class=3D""></div><div style=3D"margin: 0px; font-stretch: normal; = line-height: normal; font-family: "Helvetica Neue";" = class=3D"">But - is this example for rootdev option still right?
